angularjs causing issue when converting string to object

I am encountering an issue with a string I receive from an AJAX response:

[{
    id: "Abc",
    name: "ABCDD",
    color: "rgba(203,170,92,0.6)",
    div_class: "hotel_name"
}, {
    id: '136',
    name: 'PBss'
} ]

When I assign this string statically to a variable, it works fine. However, when I retrieve the same string from an AJAX request and use it in a variable, it does not work. Here is the code snippet causing the problem:

Code that is not working:

$http.post(urls)
        .success(function (response) {
            var x = JSON.parse(response);
            $scope.data = x;

        }).error(function (data, status, headers, config) {
            console.log('error');
        });

Working code snippet:

$http.post(urls)
        .success(function (response) {
            var x =  [{
                id: "Abc",
                name: "ABCDD",
                color: "rgba(203,170,92,0.6)",
                div_class: "hotel_name"
            }, {
                id: '136',
                name: 'PBss'
            } ];
            $scope.data = x;

        }).error(function (data, status, headers, config) {
            console.log('error');
        });

I am struggling to identify the cause of this issue. Any assistance would be highly appreciated. Thank you in advance.

Answer №1

It's possible that the outcome is already formatted in JSON. Test it without converting to JSON.

let data = result;

Answer №2

The result in your script is actually an Array. Attempting to apply the JSON.parse method on an array will not work as it requires a valid JSON string for processing.

Angular automatically handles the parsing of the response for you. Therefore, all you have to do is

$scope.output = result.info;

inside your .done function. :)

Answer №3

attempt

 var arr=[];
  arr=response;
 $scope.items=arr;

Additionally, update the JavaScript code to:

   $http.post(endpoint)
    .then(function (data1, status, headers, config) {
       var array = []; 
        array = data1;
        $scope.items = array;

    }).catch(function (data1, status, headers, config) {
        console.log('error');
    });

Answer №4

It seems like the issue lies within your JSON data.

[{
    id: "Abc",
    name: "ABCDD",
    color: "rgba(203,170,92,0.6)",
    div_class: "hotel_name"
}, {
    id: '136',//<-- This single quote characters is illegal. JSON specification states that only double quotes are allowed.
    name: 'PBss'//<-- This single quote characters is illegal. JSON specification states that only double quotes are allowed.
} ]

Have you considered trying

var x = JSON.parse(JSON.stringify((response)));

I believe this approach should fix the problem!

Answer №5

Why isn't it functioning properly? A. Are you encountering an error or is it not in the desired format?

In the code snippet provided, you attempted to use JSON.parse(). This function is typically used when a json string is sent from the server. Are you sending a json string? In other words, are you using json_encode() in your PHP file like this:

echo json_encode($result); // This converts the object to a json string which we receive from the client

Then, in the success function, we parse the object as follows:

$http.post(urls)
        .success(function (response) {
            var x = JSON.parse(response);
            $scope.data = x;

        }).error(function (data, status, headers, config) {
            console.log('error');
        });

Update

The correct json string that should be returned from the server should follow this structure:

["{\"id\": \"plazabeach\",\"name\": \"DDD\",\"color\": \"rgba(203,170,92,0.6 )\",\"div_class\": \"hotel_name\"}, {\"id\": \"136\",\"name\": \"PBss\"}"]

You can verify this by using Chrome console: JSON.parse(all the string here);
